An existing Starknet Dart application +2. Access to a SNIP-29 compliant paymaster service (e.g., AVNU Paymaster) +3. Understanding of SNIP-9 (Outside Execution) and SNIP-12 (Off-chain Message Signing) + +## Installation + +Add the paymaster SDK to your existing project: + +```yaml +dependencies: + starknet_paymaster: ^0.1.0 + # Your existing dependencies + starknet: ^0.x.x +``` + +## Basic Integration + +### 1. Initialize Paymaster Client + +Replace your existing transaction submission logic with paymaster-enabled transactions: + +```dart +// Before: Direct transaction submission +final account = Account(provider: provider, signer: signer, address: address); +final result = await account.execute(calls); + +// After: Paymaster-enabled transactions +final paymasterConfig = PaymasterConfig.avnu( + network: 'sepolia', + apiKey: 'your-api-key', +); +final paymaster = PaymasterClient(paymasterConfig); + +// For gasless transactions +final result = await paymaster.executeSponsoredTransaction( + transaction: PaymasterInvokeTransaction( + invoke: PaymasterInvoke( + senderAddress: Address.fromHex(account.address), + calls: calls.map((call) => Call( + contractAddress: Address.fromHex(call.contractAddress), + entryPointSelector: Felt.fromHex(call.entryPointSelector), + calldata: call.calldata.map((data) => Felt.fromHex(data)).toList(), + )).toList(), + ), + ), + signTypedData: (typedData) async { + return await account.signTypedData(typedData); + }, +); +``` + +### 2. Update Transaction Models + +Convert your existing transaction models to paymaster-compatible formats: + +```dart +// Helper function to convert existing calls +List convertToPaymasterCalls(List existingCalls) { + return existingCalls.map((call) => Call( + contractAddress: Address.fromHex(call.to), + entryPointSelector: Felt.fromHex(call.selector), + calldata: call.calldata.map((data) => Felt.fromHex(data)).toList(), + )).toList(); +} + +// Helper function to create paymaster transaction +PaymasterInvokeTransaction createPaymasterTransaction( + String senderAddress, + List calls, +) { + return PaymasterInvokeTransaction( + invoke: PaymasterInvoke( + senderAddress: Address.fromHex(senderAddress), + calls: convertToPaymasterCalls(calls), + ), + ); +} +``` + +### 3. Update Signature Handling + +Integrate with your existing signature provider: + +```dart +class PaymasterSignatureProvider { + final YourExistingAccount account; + + PaymasterSignatureProvider(this.account); + + Future> signTypedData(TypedData typedData) async { + // Convert paymaster typed data to your account's format + final signature = await account.signTypedData( + convertTypedDataFormat(typedData), + ); + + // Convert signature to paymaster format + return signature.map((sig) => Felt.fromHex(sig)).toList(); + } +} +``` + +## Advanced Integration Patterns + +### 1. Conditional Paymaster Usage + +Use paymaster only when beneficial: + +```dart +class SmartTransactionManager { + final YourExistingAccount account; + final PaymasterClient paymaster; + + SmartTransactionManager(this.account, this.paymaster); + + Future executeTransaction(List calls) async { + // Check if user has sufficient balance for gas + final userBalance = await account.getBalance(); + final feeEstimate = await estimateTransactionFee(calls); + + if (userBalance < feeEstimate) { + // Use paymaster for gasless transaction + return await executeWithPaymaster(calls); + } else { + // Use regular transaction + return await account.execute(calls); + } + } + + Future executeWithPaymaster(List calls) async { + final transaction = createPaymasterTransaction(account.address, calls); + + final result = await paymaster.executeSponsoredTransaction( + transaction: transaction, + signTypedData: (typedData) => account.signTypedData(typedData), + ); + + return TransactionResult( + transactionHash: result.transactionHash.value.value, + trackingId: result.trackingId.value, + ); + } +} +``` + +### 2. Token-Based Fee Payment + +Allow users to pay fees with preferred tokens: + +```dart +class TokenFeeManager { + final PaymasterClient paymaster; + + TokenFeeManager(this.paymaster); + + Future> getSupportedTokens() async { + return await paymaster.getSupportedTokensAndPrices(); + } + + Future executeWithToken( + List calls, + String senderAddress, + String preferredTokenSymbol, + ) async { + final tokens = await getSupportedTokens(); + final token = tokens.firstWhere( + (t) => t.symbol.toUpperCase() == preferredTokenSymbol.toUpperCase(), + ); + + // Get fee estimate + final transaction = createPaymasterTransaction(senderAddress, calls); + final feeEstimate = await paymaster.getFeeEstimate( + transaction: transaction, + execution: PaymasterExecution.erc20( + gasTokenAddress: token.address, + maxGasTokenAmount: token.priceInStrk, + ), + ); + + // Execute with appropriate token amount + return await paymaster.executeErc20Transaction( + transaction: transaction, + gasTokenAddress: token.address, + maxGasTokenAmount: feeEstimate.maxTokenAmountSuggested ?? token.priceInStrk, + signTypedData: (typedData) => yourSignFunction(typedData), + ); + } +} +``` + +### 3. Transaction Tracking Integration + +Integrate transaction tracking with your existing UI: + +```dart +class TransactionTracker { + final PaymasterClient paymaster; + final StreamController _statusController; + + TransactionTracker(this.paymaster) + : _statusController = StreamController.broadcast(); + + Stream get statusStream => _statusController.stream; + + Future trackTransaction(TrackingId trackingId) async { + try { + _statusController.add(TransactionStatus.pending); + + final result = await paymaster.waitForTransaction( + trackingId, + pollInterval: Duration(seconds: 2), + timeout: Duration(minutes: 5), + ); + + switch (result.status) { + case PaymasterExecutionStatus.accepted: + _statusController.add(TransactionStatus.confirmed); + break; + case PaymasterExecutionStatus.dropped: + _statusController.add(TransactionStatus.failed); + break; + default: + _statusController.add(TransactionStatus.pending); + } + } catch (e) { + _statusController.add(TransactionStatus.error); + } + } +} +``` + +## Error Handling Migration + +Update your error handling to include paymaster-specific errors: + +```dart +// Before: Basic error handling +try { + final result = await account.execute(calls); +} catch (e) { + handleTransactionError(e); +} + +// After: Comprehensive paymaster error handling +try { + final result = await paymaster.executeSponsoredTransaction( + transaction: transaction, + signTypedData: signFunction, + ); +} on TokenNotSupportedException catch (e) { + showUserMessage('The selected token is not supported for fee payment'); +} on MaxAmountTooLowException catch (e) { + showUserMessage('Insufficient token amount for transaction fees'); +} on InvalidSignatureException catch (e) { + showUserMessage('Transaction signature is invalid. Please try again.'); +} on PaymasterNetworkException catch (e) { + showUserMessage('Network error. Please check your connection.'); +} on PaymasterException catch (e) { + showUserMessage('Paymaster error: ${e.message}'); +} catch (e) { + handleGenericError(e); +} +``` + +## Testing Migration + +Update your tests to include paymaster functionality: + +```dart +// Test helper for paymaster integration +class PaymasterTestHelper { + static PaymasterClient createMockClient() { + final mockHttpClient = MockClient(); + final config = PaymasterConfig( + nodeUrl: 'https://test.paymaster.example.com', + httpClient: mockHttpClient, + ); + return PaymasterClient(config); + } + + static void mockSuccessfulTransaction(MockClient mockClient) { + when(mockClient.post(any, headers: anyNamed('headers'), body: anyNamed('body'))) + .thenAnswer((_) async => http.Response(jsonEncode({ + 'jsonrpc': '2.0', + 'id': '1', + 'result': { + 'tracking_id': 'test-tracking-id', + 'transaction_hash': '0xtest-hash', + }, + }), 200)); + } +} +``` + +## Performance Considerations + +### 1. Client Lifecycle Management + +```dart +class PaymasterManager { + static PaymasterClient? _instance; + + static PaymasterClient getInstance(PaymasterConfig config) { + _instance ??= PaymasterClient(config); + return _instance!; + } + + static void dispose() { + _instance?.dispose(); + _instance = null; + } +} +``` + +### 2. Caching Token Information + +```dart +class TokenCache { + static List? _cachedTokens; + static DateTime? _lastUpdate; + static const Duration _cacheExpiry = Duration(minutes: 5); + + static Future> getSupportedTokens(PaymasterClient client) async { + if (_cachedTokens != null && + _lastUpdate != null && + DateTime.now().difference(_lastUpdate!) < _cacheExpiry) { + return _cachedTokens!; + } + + _cachedTokens = await client.getSupportedTokensAndPrices(); + _lastUpdate = DateTime.now(); + return _cachedTokens!; + } +} +``` + +## Best Practices + +1. **Always validate transactions** before submitting to paymaster +2. **Handle network errors gracefully** with proper retry logic +3. **Cache token information** to reduce API calls +4. **Provide clear user feedback** during transaction processing +5. **Implement proper timeout handling** for long-running operations +6. **Use appropriate fee estimation** with safety margins +7. **Test thoroughly** with both sponsored and token-based transactions + +## Troubleshooting + +### Common Issues + +1. **Invalid Signature Errors** + - Ensure typed data is signed correctly + - Verify account has proper signing capabilities + +2. **Token Not Supported Errors** + - Check supported tokens list before attempting transaction + - Validate token addresses are correct + +3. **Network Timeouts** + - Implement proper retry logic + - Use appropriate timeout values + +4. **Fee Estimation Issues** + - Always use suggested amounts with safety margins + - Handle dynamic pricing changes + +For more detailed troubleshooting, refer to the [main documentation](README.md) and [API reference](https://pub.dev/documentation/starknet_paymaster/). diff --git a/packages/starknet_paymaster/README.md b/packages/starknet_paymaster/README.md new file mode 100644 index 00000000..09c1bdbf --- /dev/null +++ b/packages/starknet_paymaster/README.md @@ -0,0 +1,308 @@ +# Starknet Paymaster SDK + +[![Pub Version](https://img.shields.io/pub/v/starknet_paymaster)](https://pub.dev/packages/starknet_paymaster) +[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT) + +A comprehensive SNIP-29 compliant Paymaster SDK for Starknet Dart applications.
